SLED-PROPELLER.

Specification of Letters Patent.

Application filed March 20, 1908.

Patented Nov. 10, 1908.

Serial No. 422,303.

To all whom it may concern:

Be it known that I, CHRISTOPHER KIBAT, a citizen of the United States, residing at Belvidere, in the county of Boone and State of Illinois, have invented a new and useful Sled- Propeller, of which the following is a specification.

The invention relates to improvements in sled pro ellers.

The 0 ject of the present invention is to improve the construction of sled propellers, and to provide a simple, inexpensive and eflicient s ed ro elling device, adapted to be readily app ie to a sled, bicycle, automobile, or other vehicle equipped with motor power, and capable of enabling the same to be positively and rapidly propelled.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various c anges in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a side elevation of a sleigh, provided with a sled propeller, constructed in accordance with t is invention. Fig. 2 is a longitudinal sectional view of the same. Fi 3 is an enlarged perspective view of the s ed pro eller detached from the sleigh. Fig. 4 is a orizontal sectional view of the same. Fig. 5 is a detail view, illustrating the construction of the rear guide.

Like numerals'of reference designate corresponding parts in all the figures of the drawlngs. Y

The sled ropeller comprises front and rear propelling evlces, constructed substantially the same and arranged for successively actuating a sleigh 1, so that the latter will be positively actuated during substantially the entire period the mechanism is in operation. The front propelling device includes a pair of spaced endless sprocket chains 2, and a pair of propelling members 3, located between the endless sprocket chains and connected with the same by a transverse rod 4. The endless sprocket chains 2, which are located at o posite sides of the sleigh, are arranged on ront and rear sprocket wheels 5 and 6, which are longitudinal guides 9. The upper and lower flights of the sprocket chains are horizontal, and the guides 9, which conform to the configuration of the endless sprocket chains, are provided with terminal recesses 10 and upper and lower connecting grooves 11. "he s rocket wheels 5 and 6 are located within the end recesses of the guides, and the upper and lower grooves, which receive the upper and lower flights of the s rocket chains, are adapted to sup ort an brace the same. The guides also fbrm casings or housings for the endless sprocket chains.

The transverse rod 4 is suitably secured to the endless sprocket chains, and the propelling members 3, which consist of rods, are provided with eyes 12, receiving the transverse rod 4 and permitting the same to turn therein as the rod is carried around the ends of the guide by the sprocket chains. The propelling rods or members 3 are provided with forwardly extending arms 13, arranged in and slidable through guiding eyes 14 of a front transverse guide 15, consisting of a rod secured at its ends to the front portion of the sleigh. The guides and the arms 13 maintain the propelling rods or arms in proper osition with relation to the snow, ice, or ot er supporting surface for propelling the sled. The lower flights of the endless sprocket chains carry the propelling rods rearwardly with relation to the sleigh, and the endless chains lift the rods or arms 3 at the rear ends of the side guides'9. The upper flights of the endless sprocket chains carry the rods or members 3 forwardly, and when the latter reach the front ends of the side guides, they are carried'downwardly by the endless chains and are again engaged with the snow, ice, or other supporting surface.

The rear propelling device includes a pair of endless sprocket chains 16, propelling rods or members 17, and a transverse rod 18 connecting the propelling rods or members with the rear endless sprocket chains. The rear endless sprocket chains 16, which are arranged on front and rear sprocket wheels 19 and 20, are housed within side guides 21, provided with terminal recesses and having upper and lower grooves similar to those of the front side guides. The front and rear side guides are slidably mounted on the sleigh and are arranged below the body thereof, as clearly shown in Figs. 1 and 2 of the drawings. The rods or members 17, which are provided mounted on front and rear shafts 7 and 8 of with eyes 22 to receive the transverse rod 18,

are e nipped with forwardly projecting arm-s- 23, W rich slide througheyes 2.4 of rear transverse guide 25, having upwardly extending arms secured to the bottomiof the 5 body of the sleigh. The front and rear sprocket wheels 19-and 20 are mountedon' are mounted on the rear shafts 8- of the front propelling device, and the sprocket wheels 2 9 are. mounted on the front shafts 26 of the rear 5 propelling device.- The sprocket gearing for c'onnecting'the front and rear propelling devices are arrangedonthe exterior-of the side guides at the outer facesth'erecf, and the rear shafts 2.7 of the rear-propel ling devices are power shaft 31 of a motor3-2. This sprocket gearing comprises front sprocket-wheels 33, mounted on the rear shafts 27 and receiving endless sprocket chains 34, which extend -fromtherear shafts 27 to sprocket wheels 35, mounted on the ends of the power shaft, Thepower' shaft extends across the sleigh, the motor 32 being arranged at an intermediatepoi-nt, but any other desired arrangesegment may be employed for actuating the sled propeller; Also the sled propeller may be operated by hand or foot power, and one or more propelling devices may be employed.

The propelling rods or, members of the front and rear propelling devices are arranged so that when the front rods or members are carried into engagement "with the supporting surface, the rear rods or members will be 4o'zo'rmembers are carried rearwardly, the, rear that one pair or set of propelling rods or members will be actuating-the sled except at the instant when one is being lifted from the snow and the other is being moved downward intoenga'gement with the same. By this arrangement there will be no liability of the sled slipping" backward while being propelled up an incline.

The endless chains, which reciprocate the propelling rods or members longitudinally, operateto raise the rods ormembers at the end of the rear stroke, and they lower the rods or members at the end of the front stro'ke, and the guides through which the rods slideserve as fulcrums in the upward and downward swinging movement of the rods or members.

Havingthus fully described my invention, SO-what Iclaim as new and desire to secure by Letters" Patent, is

1.- The'combination with asled, of spaced endless chains mounted thereon, a long1tudinally' reciprocatable propelling membeiglo- 651cated between and connected withand actuc'eiving the said arms. rods or members will be carried forwardly, so

atedby the chains, and guiding means a through which the propelling member slides,

said guiding means forming a fulcrum for the propelling member.

In testimony, that I claim the foregoing as my own, I have hereto afiiXed my signature in the presence of two witnesses.
